Complementary Events
A game where there is not a chance of each player being equally likely to win
The events of one outcome happening and that outcome not happening. The sum of the probabilities of an event and its complement is 1 or 100%.
An event consisting of two or more simple events
The ratio of the number of ways an event can occur to the number of possible outcomes. It based on what should happen when conducting a probability experiment
Fair Game
An experiment hat is designed to model the action in a given situation
A game where each player has an equally likely chance of winning
The chance that some event will happen. It is the ratio of the number of favorable outcomes to the number if possible outcomes
An arrangement, or listing, of objects in which order is important
Fundamental Counting principle
Two or more events in which the outcome of one event affects the outcome of other events
An estimated probability based on the relative frequency of positive outcomes during an experiment. It is based on what actually occurred during such an experiment
Uses multiplication of the number of ways each events in an experiment can occur to find the number of possible outcomes in a sample space
The events of one outcome happening and that outcome not happening. The sum of the probabilities of an event and its complement is 1 or 100%.
Sample Space
Uses multiplication of the number of ways each events in an experiment can occur to find the number of possible outcomes in a sample space
The set of all possible outcomes of a probability experiment
An arrangement, or listing, of objects in which order is important
Any one of the possible results of an action. For example, 4 is an outcome when a number cube is rolled
Theoretical Probability
Two or more events in which the outcome of one event affects the outcome of other events
Uses multiplication of the number of ways each events in an experiment can occur to find the number of possible outcomes in a sample space
The ratio of the number of ways an event can occur to the number of possible outcomes. It based on what should happen when conducting a probability experiment
An arrangement, or listing, of objects in which order is important
